24 10/100/1000 Mbps PoE ports + 4 SFP ports Metro Ethernet Switch
Apraksts:
The DGS-1510/ME Series Metro Ethernet Switches are a family of Ethernet switches ideal for Metro Ethernet applications. They feature a variety of ports, including 10/100/1000BASE-T RJ-45 ports, 1G SFP ports, and 10G SFP+ ports for increased network bandwidth. Surge protection, advanced Layer 2 functions and a suite of security and management tools make the DGS-1510/ME Series Metro Ethernet Switches ideally suited for Metro Ethernet applications.
 
Multi-Gigabit Performance
The DGS-1510/ME Series Metro Ethernet Switches come with a variety of port types, including Gigabit Ethernet RJ-45, 1 Gigabit Ethernet SFP ports, or 10 Gigabit Ethernet SFP+ ports. All models offer a minimum of at least 2 Gigabit Ethernet SFP ports. The DGS-1510-28X/ME, DGS-1510-28XS/ME and DGS-1510-52/ME offer 4 10 Gigabit Ethernet SFP+ ports for improved uplink bandwidth. The DGS-1510-28LP/ME and DGS-1510-28XMP/ME switches feature PoE, allowing compatible devices to be installed in remote locations without immediate access to power outlets.
 
Efficient and Resilient Networking
All Ethernet ports in the DGS-1510/ME Series support 6 kV surge protection, protecting the switch from power surges due to lightning strikes or faulty electrical cabling. The switches can be used with a D-Link DPS-500A/DPS-500DC Redundant Power Supply (RPS) or a 12 VDC backup connection to ensure continuous operation. The DGS-1510/ME Series support ITU-T G.8032 Ethernet Ring Protection Switching (ERPS), which allows 50 millisecond failover in the event of a failure of one of the rings, minimizing service disruption. The switches also support IEEE 802.1AX and 802.3ad Link Aggregation, which allows grouping of multiple ports to provide redundancy and load balancing in mission-critical environments.
 
Triple Play Services
The DGS-1510/ME Series Metro Ethernet Switches feature a full suite of Layer 2 multicast functions, including IGMP snooping, IGMP filtering, fast leave, and multicast traffic configuration for specific ports. With L2 multicast support, the DGS-1510/ME Series is ready and capable of handling the growing demand for IPTV applications. Host-based IGMP/MLD Snooping allows for multiple multicast subscribers per physical interface, and an Internet Standard Multicast (ISM) VLAN separates multicast streams in a multicast VLAN, saving bandwidth on the backbone network. The ISM VLAN profiles allow users to bind the predefined multicast registration information to subscriber ports quickly and easily. The DGS-1510/ME Series also supports IGMP authentication, which can prevent rogue IPTV subscriptions by authenticating set-top boxes as well as channel switching to secure Internet Service Provider (ISP) revenues.
 
Quality of Service
The DGS-1510/ME Series supports advanced Quality of Service (QoS) functions to help ISPs reliably deliver high-quality triple play services. Flexible packet classification can be based on various header fields or user-defined packet content to help administrators prioritize network traffic. The Bandwidth Control feature allows ISPs to define the upstream/downstream throughput levels for each port with granularity down to 64 Kbps.
 
Robust Maintenance and Troubleshooting
The DGS-1510/ME Series feature a complete set of Operations, Administration, and Management (OAM) features to reduce maintenance costs and simplify management. Cable diagnostics display the status of Ethernet cables and allow support staff to detect cable errors remotely, reducing on-site support costs. The 802.3ah Ethernet Link OAM and 802.1ag Connectivity Fault Management (CFM) standards provide administrators with tools to effectively monitor and manage Ethernet networks. This allows service providers to monitor customer connectivity, isolate network issues and optimize network performance.
 
Security & Authentication
The DGS-1510/ME Series offer user and device authentication features such as 802.1X port-based access control and MAC address-based access control. This allows devices to be authenticated based on their MAC address, removing the need for client software and ensuring device compatibility. Host-based authentication and authorization provide the option to finely control network access for each device on the network. Advanced features such as RADIUS accounting allow the switches to be integrated with back-end systems for billing or advanced access control. The DGS-1510/ME Series support address and interface binding features such as IP-MAC-Port Binding and ARP Spoofing Prevention to protect against Man-in-the-Middle or ARP Spoofing attacks.
